The FOGLight (Fall Of Ground) indicator is an early warning device designed to detect and warm mining crews of separation in the rock above, helping to prevent losses and providing a safer work environment underground. The FOGLight is simple to install, manufactured from tough materials and has a highly visible flashing LED indicator to highlight potentially unsafe movement in the hanging wall.
Simple to install
Available with single and dual indication
Cannot be reset once triggered
12 month plus battery life
Available in various lengths and displacement settings
The Dual FOGLight includes the LED functionality of the standard version but includes a second and independent mechanically activated trigger. The Dual FOGLight is manufactured with a reflective green assembly around the housing of the FOGLight which is designed to disengage from the FOGLight and fall away at the pre-set trigger displacement . This then exposes the housing of the FOGLight which is in reflective Amber and provides a distinct visual warning that the unit has detected excessive hanging wall movement. The mechanical component of the Dual FOGLight provides a fail-safe redundancy for the electrical LED system.
